I read Chmel's assessments a few years ago. While his findings on those samples may have value, I would have liked to see him test multiple samples and average them out. It might also have given an indication of consistency and quality control.
I wonder, too, if he chose to play the Hohner Super 64 after his tests, or before. There may be an unintended bias in his findings.
Since these tests were done, Suzuki has redesigned some features of both models that Chmel tested. The SC now has a mouthplate with round holes, and the SCX has a better designed mouthplate. Both are now more rounded as seen in section.
For the SCX, anyway, this would affect some of his findings. The new SCX wouldn't leak as badly, which may affect the consistency of response through all octaves.
I don't remember whether Chmel discusses warranty, but that has changed also. Hohner USA continues to have good customer service. Suzuki is going out of its way, as Danny has reported, to take care of its customers, especially in replacing reeds or reedplates; that's how secure they feel about their welds. Seydel now has a USA representative in Rupert Oysler, and excellent choice. And Hering now has Harp House taking care of their warranty work.
The significant item here, in my opinion, is Suzuki's warranty of its reed welds. This should allay some of Chmel's (and our) misgivings about having to replace reeds.
In sum, these are tests that are in some cases outdated, by someone who didn't test multiple samples (as far as I know), and may have an unintended bias toward his chosen instrument. The comparison tests are generally worthwhile for the time they were done; but it's worth our while to keep up to date on recent changes and developments, including prices.
